There are various reasons why the moon has served as a reference point for so many watches and timepieces over the years, but now a watch with a stronger connection to the moon than any of them is going up for auction. It’s the Apollo 15 Lunar Surface Chronograph, worn on the moon by Commander Dave Scott on NASA‘s Apollo 15 mission in 1971.

The Apollo 15 Lunar Surface Chronograph, being put up for auction by RR Auction, is a Bulova Chronograph that served as a backup for Scott’s officially issued Omega watch. Following a long journey to the moon and back again, it can now be yours, if you’ve got what it takes to be the highest bidder (which is probably easier than becoming an astronaut and going to the moon, especially nowadays).

The bidding starts on October 22nd, and you can get a lot more information on Dave Scott’s Apollo 15 Lunar Surface Chronograph over at AA Auction’s listing for the watch right here.
